1-flip the camera around to frame a headshot using what many call portrait camera orientation; her lopped off chin is not attractive.
2-Ah, that's better camera orientation, but the white balance is decidedly a bit, uh, yellow. That big expanse of open sky behind you gives the same big upper-eyeball catchlights as in shot 1.
3-Cutting the top of her head off while simultaneously getting rid of the red lettering on the door behind her is not a good tradeoff. The cropping of of one hand and the fingers of the other hand is a bit jarring. it appears that yuo used flash in shot #3,as the harsh shadow on her arm shows.
All three are focused well and all three show decent rapport with your subjects, who I assume are your friends. You're doing okay, but a bit more planing might make your shots come out with more impact.
